Technical Specifications

Note: Electrical ratings depend on the supply voltage and operating conditions. The supplied dimensions and weight are retained as listing information. Confirm the exact physical dimensions and shipping weight against the actual unit before installation or transportation.

Function and Working Principle

The 2198-P031 performs the AC-to-DC power conversion required by the Kinetix 5700 servo drive system. It supplies a shared DC bus that distributes electrical energy to compatible inverter modules.

1. AC Input Power Conversion

The module receives three-phase AC power from the industrial electrical distribution system. Its power-conversion circuitry processes the incoming electrical supply and produces DC power for the servo system.

The supported input voltage range is 195–528 V AC, three-phase. This allows the module to operate in compatible 240 V and 480 V-class installations.

Correct input voltage selection, circuit protection, grounding, and wiring are essential for safe and reliable operation.

2. DC-Bus Power Distribution

After conversion, DC power is supplied to the shared DC bus. Compatible Kinetix 5700 inverter modules connect to this bus and use the available electrical energy to control their associated servo motors.

This modular arrangement allows multiple servo axes to operate within one coordinated drive system.

The 2198-P031 provides a continuous DC-bus output current of 10.5 A and a continuous output power rating of 7 kW. These ratings must be considered when calculating the total power demand of the connected servo axes.

3. Peak Current Capability

Servo systems may experience temporary increases in power demand during acceleration, deceleration, and changes in mechanical load.

The 2198-P031 supports a peak DC-bus output current of approximately 31.6 A for up to one second, subject to the specified duty-cycle restrictions.

Engineers should evaluate both continuous and peak power requirements when designing a servo system. A power supply should not be selected solely according to the sum of motor nameplate power ratings.

4. 24 V DC Control Power

In addition to the main AC input, the module uses a 24 V DC control power supply. This control power supports the required control circuitry independently of the main power-conversion function.

The specified control power input is 24 V DC ±10%. The control power supply must have sufficient capacity for the connected system and should be wired according to the manufacturer’s instructions.

5. Shared Energy Architecture

The Kinetix 5700 system uses a shared DC-bus architecture. This arrangement allows compatible inverter modules to draw power from a common DC-bus source.

In suitable applications, energy generated by decelerating servo axes may be available to other axes through the shared DC-bus architecture, subject to system configuration and operating conditions.

This approach can help simplify power distribution in multi-axis machinery compared with designing every servo axis as a completely independent drive system.

Role in Industrial Automation Systems

The 2198-P031 is an important power component within a Kinetix 5700 servo motion-control system. It provides the electrical foundation required by the inverter modules that directly control servo motors.

1. Integration with Servo Inverter Modules

The DC-bus power supply connects to compatible Kinetix 5700 inverter modules through the system’s shared bus arrangement.

The inverter modules use the DC-bus power to generate controlled motor output. This allows servo motors to perform precise movements according to the commands issued by the motion controller.

The number and type of inverter modules must be selected according to the available DC-bus capacity and the system’s electrical requirements.

2. Integration with PLC and Motion Controllers

The Kinetix 5700 platform can be integrated with Rockwell Automation control systems, including suitable ControlLogix and CompactLogix controllers.

The controller executes the machine logic and motion commands, while the servo drive system supplies the electrical power and motor-control functions.

A typical system may include:

• ControlLogix or CompactLogix controller.
• Kinetix 5700 DC-bus power supply.
• Compatible Kinetix 5700 inverter modules.
• Servo motors and feedback devices.
• EtherNet/IP communication infrastructure.
• Safety and emergency-stop circuits.
• Industrial power distribution and protective devices.

The exact configuration depends on the machine’s axis count, motor requirements, safety architecture, and communication design.

3. Multi-Axis Motion Coordination

Industrial machines often require multiple motors to operate in coordination. Examples include packaging lines, robotic handling equipment, and synchronized production machinery.

The 2198-P031 supplies the DC-bus power needed by compatible inverter modules, allowing the servo system to support coordinated movement across multiple axes.

The motion controller manages the movement commands, while the power supply provides the required electrical energy.

4. Power Distribution and System Reliability

A properly designed DC-bus power architecture helps organize electrical power distribution across the servo system.

The power supply must be matched to the connected inverter modules and the expected operating profile. Engineers should evaluate continuous power demand, peak current, input supply conditions, and system protection before commissioning.
